Turkish Airlines Miles&Smiles - WiFi availability on flight between IST and North america

I read somewhere that TK provides complementary WiFi for flights between IST and North America, though it will be charge in the future.

But I could not find this info on TK website. I will fly with them next week. Can anybody confirm that whether there's WiFi on these flights? Thanks.

Yes they have just started this service. It wasn't working on my LAX-IST flight on Feb 23rd, but it was working on the return trip on 28th. They didn't even announce it until halfway in flight, I just found out by luck.

The service is free (probably only for a limited time) and works very well for a trans-atlantic flight.

They equipped only few aircrafts so far. I am posting this from TC-JJN on LAX-IST and live TV + internet works well indeed. To my knowledge the other a/c equipped is TC-JJP. Looking at their recent itineraries they are deployed most often on LAX, JFK and HKG routes.

While on the ground you can spot whether it has internet by a small "hump" on top of the front business cabin, while in-flight there is a big sign in front of each cabin, as well as staff announcements after take-off.
